California hosts a largely hidden and fast rising grid of dispersed diesel generators; these low buzzing large boxes located at internet server farms, hospitals, police stations, and, during Outside Lands, diesel generator set Golden Gate Park. In 2018, roughly 6,500 again-up generators, often known as “BUGs,” had been littered across the San Francisco Bay Area, in a position to power up a collective 3,810 megawatts (MW). In 2021 – less than three years later – BUG deployment had reached 8,722 generators, 4,840 MW of energy supply, a 34 % bounce in the back-up generator fleet.
There are enough Bay Area BUGs to gentle up greater than two San Francisco’s, on a day when demand is at its absolute highest.
Similarly, in 2020 there were 12,104 again-up generators totaling 2,697 MW of capacity in the realm regulated by the South Coast Air Quality Management District. Just a yr later this population had grown to 14,785 BUGs, 7,360 MW capability, a 22 percent increase within the swarm.
California’s electricity grid can supply about eighty gigawatts of energy. BUGs within the Bay Area and South Coast alone can generate roughly 15 p.

Throughout the state larger generators are being deployed extra rapidly. Nearly ninety % of back-up generators positioned in the Bay Area and South Coast are diesel fueled.
Residential generators, that are largely unregulated, and for which inhabitants data are unavailable, are similarly flying off shelves, like so many cicadas waking up from a long sleep. Despite boosting production of standby residential generators with a brand new South Carolina plant, Waukesha-based Generac Power Systems, the most important supplier of house-based BUGs, has a six-month backlog and is contemplating including a West Coast manufacturing facility.
diesel power generator generators tend to be situated near the place individuals reside, work, and attend faculty. They frequently squat in communities that’re already subject to multiple pollution sources, as measured by CalEnviroScreen, which maps pollution burdens all through the state. Ironically, given state and local local weather and net zero emission targets, the general public sector is amongst essentially the most voracious BUG adopters. In South Coast, governments owns nearly 14 % of the population, with well being care services accountable for an additional roughly 10 %. Within the Bay Area, the public sector accounts for thirteen % of nonresidential generators.
Legislators, protecting of taxpayer monies, deploy BUGs as a low-cost resolution to reliability points. But they’re a significant source of greenhouse gases, particulate matter (PM), unstable natural compounds (VOCs), nitrous oxides (NOx), and sulfur dioxide, which might create smog and exacerbate respiratory situations, like asthma, chronic obstructive pulmonary disease, and lung cancer, especially for kids and older adults.
Non-residential BUG use within the Bay Area and South Coast alone produces annual emissions of no less than 86,899 metric tons of carbon dioxide (MTCO2), power generator set roughly 20 MT of fine PM, 62 MT of VOCs, and almost 1,000 MT of haze-inducing NOx. This pollution, in turn, might trigger upwards of $136 million of well being costs a yr, as a result of will increase in mortalities, heart attacks, hospital visits and other hostile penalties. Costs related to the statewide fleet of BUGs, in addition to residential generators, are much higher.
Data associated to the variety of hours that prime diesel generator set generators operate is self-reported, with little regulatory scrutiny. The degree to which BUGs run is influenced by a number of things, together with wildfires, Public Safety Power Shut-offs, severe weather, and potentially their use to arbitrage more and more expensive electricity prices.
In California, non-residential BUGs are individually permitted by one in all 35 air districts during which they’re positioned. Their cumulative magnitude is basically hidden; knowledge from the districts shouldn’t be meaningfully aggregated or reported on the state stage.
Absent new coverage directions, the role diesel generation performs in California’s power mix will continue to extend. On the lookout for low-value and expediate methods to ensure reliability within the face of potential supply shortfalls, Governor Gavin Newsom and regulators have greenlit nearly unrestricted use of diesel generators within the near future.
